Which unit in the Haven castle do you like the most (based on its appearance)?

The angels there are quite normal. As far as I understand, the image of angels in Heroes 3 is based on some biblical source. Why not come up with something new? They look quite impressive there, especially the fallen ones.
By the way, I think I can tell the difference between a boy and a girl, but I don't understand why you think they are women??? (by the way, as far as I know, in some versions, angels are genderless).
